Bv @/@m` my ,47'TORN Y Filed dan. 20, 1958, Ser. No. 710,065 9 Claims. (Cl. 242-27) This invention relates generally tomachines for manufacturing devices employed in the art of weaving, and the like, and more particularly it pertains to an improved machine for the winding of cops, which are specially wound bodies of yarn for use on weaving machines.

In the manufacture of cops on existing machines, an individual spool, or bobbin, is required for each cop. These spools are of Wood or other rigid material, and, because of their cost, and or expenses incurred in storing and handling them, the lspools add measurably to the cost of the finished cop. Other limitations of existing cop winding machines are their large size, complexity, and need for frequent operator attention and adjustment.

It is, therefore, a principal object of this invention to provide a new and improved cop winding machine which fashions self supporting cops, of perfect form and tension, entirely without the use of individual spools or bobbins.

Another object of this invention is to provide a copping machine that winds cops sequentially and rapidly, cutting off and ejecting each cop as it is made, in a continuous, automatic process.

A further object of this invention is to provide a copping machine in which the length of the cops produced is variable through a considerable range of adjustment.

A further object of this invention is to provide -a cop ping machine, which lis compact in structure, and economical and reliable in operation.

Another object of this invention is to provide a new and improved copping machine in which yarn from a suitable supply is fed, under controlled tension, through a traversing mechanism and onto interim spool means, including a rotating spindle, on which the yarn is Wound into cop form, and from which the finished cop is severed and ejected, all by `automatically operating mechanisms.

These and other objects of this invention wi-ll become more readily `apparent through examination of the drawings, which describe a single embodiment of the device, and in which:

Referring now to FIGURE l, and to FIGURE 5, which is a detail of FIGURE l enlarged, the motions and structures of those parts of the copping machine which actually touch the yarn will be described, after a brief account is given of the gross exterior features of the machine. Description of the .remainder of the machine, including the internal structures which drive and synchronize its various par-ts, will be given subsequently.

The machine 45, as shown in FIGURE 1, rests on a platform 13, supported by angle iron frame 10. A lower platform 11 -holds the drive motor 12. A removable Icasing covers much of the machine.

The cop 80, as shown in FIGURE 14, which consists of a quantity of yarn wound in a particular manner, is formed directly on spindle 84, as shown in FIGURE 5, which rotates continuously.

As a strand of yarn `40, `as shown in FIGURE l, from a suitable source of yarn, is fed downwardly onto the spindle through slot `87 in funnel 72 with the -strand being oscillated continually from one end of the spindle to the other by a traversing fairlead 32, which is fixed on axially oscillating shaft 30. This combination of winding and oscillation produces a body of `smoothly overlapped layers of yarn on the spindle. As this wound body, or cop, increases to the maximum diameter, which can be held inside funnel 72, it is gradually and continuously forced off the tapered spindle by the incline of the funnel bore, and so increases in length gradually and continuously.

Initial increase in cop length brings the advancing end 113, Ias shown in FIGURE 14, of the cop into contact with a rotatableheadpiece 39, as shown in FIGURE l, which is mounted on a slidable channel member 33 extending through the structure 45. Continued increase in cop length proportionally forces the headpiece 39 axially laway from the `spindle 84.

When it has been displaced a predetermined distance (the cop-length setting) -by increase in cop length, the headpiece, acting on channel 13, `actuates mechanism-s which remove it from contact with the cop, sever the strand of yarn 40 from the cop, and yeject t-he cop from the machine by causing funnel 72 to move the cop axially of the `spindle 84` The cop falls from the machine into any suitably placed container means, :and the machine resets itself and winds further cops as required, in the automatic sequence described.

It should be noted here that the cop is cut free at a point between cop and spindle, not between spindle and yarn supply, so that the spindle is at all times engaged to the supply of yarn. 'I'he cutting function will be explained further subsequently.

, Thus, in the manner described, coreless, self supporting cops are produced by the machine of this invention, in contrast to cops which must be wound on expensive individual spools, if produced by conventional cop winders.

FIGURE 1 also shows vthe structures for holding the spool of supply yarn, and for dispensing the-yarn uniformly. Mast 74, fixed vertically to the top of casing 75, supports the spool of yarn 73, from which the strand 40 is pulled lby spindle 84. The strand is pulled from the spool 73 through fairleads including disk 7S and eyelets 81, and through av spring-loaded friction sheave 77, of conventional split form, which keeps the yarn suitably taut for cop winding. Continuing, the yarn passes over arm 82 of switch 83.

v In case of yarn breakage, the arm 821'5 39 lQngQr de pressed by yarn tension, and under pressure of spring means, not shown, rises and opens switch 83. As shown in FIGURE 15, this interrupts the flow of electric current through conductor 79, and stops the drivemotor 12, and the cop winding machine.

Continuing past the switch arm, the yarn passes finally through the traversing mechanism and the opening in the funnel, and is made up in cop form on the spindle and against the headpiece, as previously described.

FIGURE 3 best shows the methods of actuation of the machine, and largely shows the machine proper. Housing the machine, and bearing many of its pants are rear wall 14, left side wall 17, and front wall 15. Right side wall 16 is not shown in this sectional view.

The housing comprised of the walls is open at the top, but includes a oor 89 at the bottom. This floor is preferably bolted to platform 13 shown in FIGURE 1, suitably matched holes being provided in both structures for the purpose.

Openings (not indicated on the drawings) provide for passage of belt 22. which transmits power from the drive motor to the machine, and for cable 94. Sheave 93 is also mounted on floor 89 to carry the cable 94 that suspends counterweight 90.

A winding shaft 18, which is detailed separately in FIGURE 7, runs longitudinally through the structure 45, FIGURE 3, and is journalled in bearings 20. It bears integrally fixed in its end the spindle 84, FIGURE 5, on which the yarn is wound into cops. The spindle is of polygonal cross-section to give it greater purchaseon the yarn. A pulley 21 on the winding shaft is aligned with the pulley 23 on the drive motor 12, FIGURE 2, with the transmission belt 22 connecting them. The shaft 18 is employed to transmit power to two auxiliary shafts 19 and 29 and their respective mechanism. The auxiliary shaft 19 actuates axially oscillating shaft 30, FIGURE 3, through the eccentric 26, the pin 27, and the connecting rod 28. These parts are shown separately, in subassembly, in FIGURE 8. The traversing fairlead 32, adjustably clamped to shaft 30, guides the yarn 40 in spreading it over the cop ybeing Wound, as was explained in connection with FIGURE 1. The shaft is suitably journalled in the walls of the structure 45. The fairlead 32 is made adjustable on shaft 30 lengthwise, to enable it to be accurately positioned to suit its work. The shaft 19 gets its power from the worm 24 meshing with the gear 25, keyed to it. The traversing mechanism runs continuously with the shaft 18. In contrast with shaft 19, and its traversing mechanism, which run continuously, shaft 29, with its train of mechanism, is driven intermittently by shaft 18 through a clutch. The purpose of this intermittent drive of shaft 29 is to actuate the funnel and knives which eject and cut free each cop after it is completed, in a manner now to be explained in detail.

As shown in FIGURE 4, shaft 29 is journalled in plate 17. The shaft has a clutch 95, FIGURE 4 and 4-A, slidably keyed to it, and tensioned by a spring loaded plunger 96 in a lateral direction. A traveler plate 50 of circular form is xedly mounted on the shaft 29 and is rotated with it when the prongs 97, FIGURE 4-A, of the clutch 95, are forced, by the' tension of the spring 96 into recesses 98 in the hub 92 of the gear 63. Gear 63 is driven continuously by worm 85 on shaft 18, and turns freely on shaft 29 when clutch 95 is disengaged. As shown in enlarged detail in FIGURE 10, as well as in FIGURE 11, a step 100 projects from the left lateral face of the traveler plate 50, and is contoured angularly to facilitate the 4 elsewhere in the drawings. When the ball 102 of shifter 101, FIGURE 4-A, is brought into contact with the step 100 by rotation of traveler plate 50, the shifter is pivoted laterally until it disconnects the clutch 95 from the `gear hub 92, and the clutch and traveler plate stop. The step 100 is of relatively short angular length, subtending about of arc on the traveler plate. Its purpose is simply to stop the traveler plate at the proper moment, and then when the plate is slightly rotated by pawl means, to slip the clutch into contact, so that the plate can further travel through some 350. The short push required to move the traveler plate the remaining 10 (approximately) is furnished by the pawl mechanism 48, FIGURE v bottom of knives 70,'FIGURE 13.

16, pushing against notch 49 in the peripheral face of the traveller plate, as will be explained later in connection with FIGURE 16.

As shown in FIGURES 3 and 4, a connecting rod 60 at one end is pivoted eccentrically on the side of traveler plate 50, and at its other end is pivoted to doing beam 61, in such m-anner that rotation of the traveler plate gives a reciprocating stroke to the `doiing beam. lThe doing beam 61 is supported on rollers 62, FIGURES 4 and 16, which are suitably attached to wall 16. The rollers reduce friction, during operation of the beam. The dong beam 61 as shown in FIGURE 3, runs longitudinally -in the structure 45 and passes through the front wall 15 into a carriage 64 to which it is integrally fastened and which it reciprocates. As best shown in IFIGURE 5, the carriage 64 is of angular form, its back wall 66 in the retracted position coming back against the front wall 15,

l its bottom 67 encompassing and being yguided by the outer edges 104 of shelf 65. Spindle 84 passes through a hole in the back wall of carriage 64. The shelf 65 is rigidly attached to front wall 15 and has grooves 68, FIG- URES 5 and 12, in its top surface throughout its length. The grooves 68 are converged as shown, and serve to give a transverse travel to the tongues 69 projected from the The knives 70 are flat and of suitable thickness to slide laterally in a vertical internal slot in the back Wall 66 of the carriage 64 and against each other. The tongues 69, FIGURE 13, extend vertically down from the bottom of the knives into the horizontally disposed grooves 68, FIGURE 12, so that when the carriage 64, FIGURE 5, moves near its extreme forward position, at which point the knives `are clear of spindle 84, the knives will slide sidewise or transversely with respect to the axis of the spindle and cause the knife edges 88 to pass one another in `a shearing maner to sever the yarn and free the completed cop. The enlarged circular slots 86, FIGURE 13, in the knives allow them to clear the spindle when the carriage 64 is in the retracted position, as in FIGURE 5.

- the spindle 84. The end of spindle 84 is tapered and of traveler plate.

movement of a conventionally designed shifter 101 to depolygonal cross-section to facilita-te the winding of the yarn on it and to allow slipping of the finished cop. At theend of the stroke on the return, the step on the traveler plate moves the shifter -and clutch and stops the As previously stated, spindle 84 extends through an opening in the carriage when the carriage is positioned `against the wall 15, as in FIGURE 5, and into a funnel 72 attached to the wall 66. As said, the funnel is open at the top as indicated at 87 to permit the yarn 40 to oscillate easily and at the same time form ya mold for the cop end portion. The opposite end portion of the cop is formed by frustrum head piece 39. The opposition of spindle and headpiece is best seen in FIGURES 1 and 7.

Cop length is controlled, as Was explained in connection with FIGURE 1, by headpiece 39, through its attached gauging mechanism. FIGURE 6 details the structure of this gauging subassembly, which in essence simply bears the headpiece and an adjustable stud 37. The structure comprises headpiece 39, axle 41 on which it rotates, bracket 42 which aliixes axle 41 to channel 33 rigidly and in parallel alignment, counterweight clamp 119, whose function will be explained l-ater, longitudinal slot 38 in channel 33, screw 34 which is conventionally journalled in channel 33 so that it can rotate freely but not translate, knurled wheel 36 affixed to screw 34, nut 35 on the screw, stud 37 axed to the nut in such manner as to act both as a nut Wing and as an actuating stud, and pointer 108 axed to the stud 37. FIGURE 9, a partial section, details the nut and its immediately associated parts in perspective. `Graduations of the cop-length scale 11i) to which pointer 198 refers, can be seen on the channel. As shown in FIGURE l, channel 33 extends beyond the carriage 64 in front of the housing structure 45 at one end, and beyond the rear wall 14 at the other. Where the channel extends rearwardly, wheel 36 enables the user to turn the screw 34 and adjust the nut 35 to suit the length of cop required, referring to Vgraduations on the cop-length scale 110 to which the pointer 108 on the stud 37 is directed. The walls 14 and 15 have square holes in them for the member 33 to pass through and to hold it in line and prevent rotation.

A detailed operation of cop-length control in the copping machine of this invention will now be given. As

indicated, the cop Si) in being wound, is made upon the* spindle S4 within the funnel 72 and against the headpiece 39, FIGURE 1. As the cop is built up on vwinding, it increases in length. As the length increases, the cop pushes against the headpiece 39 and forces it outwardly. The bracket 42 and channel member 33 follow in the direction in which the headpiece is pushed by the enlarging cop, until, eventu-ally as shown in FIGURE 16, a left side elevation, the stud 37 on nut 35, set at the desired cop length, comes into contact with the tooth 43. As further shown in FIGURE 16, the tooth 43 is extended from a latch 44 that is movably connected by a hinge 59 to one end of a lever 47, which is pivoted ona stationary pin 46 near its center. The pin 46 is attached to the wall of the housing structure through bracket means, not shown. A pawl 48 extends from the lever 47 and engages a notch 49 in the traveler plate 50 when the latch 44 is moved t0- wards the front or left, through action of stud 37 on tooth 43. This rotates the traveler plate clockwise about The pawl 48 is held against the traveller plate by spring means, not shown.

The latch 44 has its free front end 56 angularly formed and disposed beneath and against the upper jaw 57 of a horizontal hasp 58 which is rigidly supported by the housing 16. A spring jaw 111 of the hasp resiliently supports the latch-end upwardly. When the latch 44 is moved towards the front (that is to the left), the hasp 5S tilts it downwardly, until at the end of the stro-ke, the stud 37 is released from the tooth 43. iStud 37 is next engaged by cam 120 atlixed to the side of the traveler plate, and through the stud, during subsequent rotation of the traveler plate, the cam pushes headpiece 39 well free of the cop. The latch 44 then springs back to become inoperative. The aforesaid 10 rotation of the traveler plate by the pawl 48 is enough to move the step 100 from under the shifter 101 and bring the clutch 95, yFIGURE 4, into action. The traveler plate continues tol rotate under power from gear 63 to which it is now engaged. When the gear drive takes over, the carriage 64 is moved forward by connecting rod 60, FIGURE 3, the snipping of the yarn by the knives 70 follows, and the cop is ejected. The carriage retreats with the yarn continuing to Wind on the spindle. The headpiece, bracket, and channel follow, being pulled back by the counterweight 9i). The counterweight is fastened to adjustable clamp 119 on channel member 61 by a cable 94 passing over sheave 93, the latter being supported by the oor 89. The cable passes downwardly, over the sheave, to the counterweight 90. The traveler plate 50, FIGURE 16, stops automatically when the step 100 throws the clutch 95 and disconnects it from the driving gear 63. At this instant its notch 54 is caught by pawl 53 and the traveler plate is stopped from overrunning. .Pawl 53 is automatically disengaged, at the start of the next cycle of operation of the traveler plate, by pivotal action about pin 46 when latch 44 is moved forward.

In the foregoing account of how cops` are Wound, and their lengths set, on the improved copping machine of this invention, -no measure has been given of the longest cop which can be made on the machine. The size of the cop so produced is limited by its capacity to sustain itself. Practically, this is not a problem, as the conventional length ot" "a cop is less than 12 inches. In special cases Where considerably greater length may be required, it is simply necessary to provide greater depth to achieve the necessary rigidity.

While but one construction of the invention has been illustrated in the drawings and described herein, it is not intended to limit its design and manufacture to such particular form, as it is appreciated that other structures could be designed and -made that Would use the same principles and come within the scope of the appended claims.
